FIELD OF THE INVENTION

The invention relates generally to modular building construction and, more particularly, to a modular frame system using light-gage metal in building construction and connection mechanisms for columns, beams, trusses, and other frame components designed to provide a modular assembly building construction that makes efficient use of materials and labor.

BACKGROUND OF THE INVENTION

Modular building construction can have the advantages of cost-effectiveness and ease of assembly over convention building construction. Fully modular building frame systems, however, are still not commonly seen. As conventional building construction costs continue to escalate, modular building construction that can provide savings in cost of labor and materials presents an attractive alternative. The modular building components can be manufactured on-site or off-site, and then moved into position to form the building frame. There is a need for a more fully modular frame system that is easy and quick to construct and makes efficient use of materials and labor.

FIG. 11 shows (a) a schematic perspective view of a truss to column connecting mechanism; and (b) a side view thereof. At this upper end truss connection, a column connecting member 150 is welded to the truss 152 which is configured to rest on a slot at the top of a column (see slots 212 of column 210 in FIG. 15). The column connecting member 150 includes a longitudinal body 153 extending across and received into the slot of the column, and a transverse flange or choke holding end 154 connected to the longitudinal body 153 and having a slanted surface 156 facing inwardly toward the truss 152. A wedge-shaped choke 158 cooperates with the inclined inner surface 156 of the column connecting member 150 and is disposed between the slanted surface 156 and the column wall to secure the connection between the truss 152 and the column.

FIG. 12 is a schematic perspective view of another truss to column connecting mechanism. At this lower end truss connection, a column connecting member 160 is welded to the truss 162 which is configured to rest on a slot 164 at the top of a column 166.

A wedge-shaped choke 176 is configured to be disposed between the slanted surface 174 of the proximal transverse flange 172 and the inner surface of the column wall.

The connecting mechanisms of FIGS. 11 and 12 provide alternatives to the use of the column cap 12 of FIGS. 8-10 when the use of the column cap 12 is not possible or desirable for any reason. The angles of the connecting members in FIGS. 11 and 12 should follow the slope of the truss. Some typical angles can be modularized to standardize production.

5. Truss to Beam Connection

FIG. 13 is a schematic view of a truss to beam connecting mechanism. A truss 180 has at an end thereof protrusions or tabs 182 that are slidably coupled into key slots 184 provided on a beam 186.

FIG. 14 is a schematic view of another truss to beam connecting mechanism. A truss holder 190 is fastened to the beam 192 for connecting with a truss 194. The beam 192 is connected to a column. The truss holder 190 includes a holder base 196 mounted to the beam 192, and a pair of spaced holder supports 198 extending from the holder base 196 to receive the truss 194 therebetween. The pair of spaced holder supports 198 each include an aperture 200 for a fastener to pass therethrough to fasten the truss 194 to the pair of spaced holder supports 198. The holder base 196 may include a threaded nipple 202 to be screwed into a threaded hole of the beam 192 for mounting to the beam 192.

FIG. 15 is a schematic perspective view of a column 210 having four slots 212 at an upper end thereof. The length of the column 210 is equal to the distance from the bottom of the column to the top of the beam that needs to be supported. Some typical lengths can be chosen. The length of the slots 212 should match the beam height or truss height. Accordingly, some standard lengths can be used.

FIG. 16 is a schematic perspective view of an extension sleeve 220 for a beam or column. The extension sleeve 220 is slightly smaller in cross section than the beams or columns and fits partially inside the beams or columns. The holes 222 are provided for coupling to the beams or columns using fasteners. The holes 222 may be threaded or built-in nuts may be provided at the holes 222. The extension sleeve 220 is connected between two beams or two columns to form a longer beam or column. Using the extension sleeve 220, all beams or columns can be modularized into a few sizes.

FIG. 17( a) shows a schematic perspective view of an end of a beam or column 240 for connecting to the extension sleeve 220 of FIG. 16. The openings 242 are configured to matching the holes 222 of the extension sleeve 220 for coupling by fasteners. FIG. 17( b) shows a sectional view along A-A of FIG. 17( a) of only the left and right openings 242, omitting the sections with the top and bottom holes 242.

FIG. 18 shows (a) a left side view, (b) a front view, and (c) a right side view of a threaded bolt 250. The threaded bolt 250 extends through each of the openings 242 of the beam or column 240 and the holes 222 of the extension sleeve 220 to connect the beam or column 240 to the extension sleeve 220.

For the connecting mechanisms employing chokes in FIGS. 3, 11, and 12, the slanted surfaces on the transverse flanges serving as choke holding wings are important for holding the chokes and keeping them from coming loose. The chokes preferably have extra length so that after they are hammered tight against the surfaces, the narrow ends of the chokes can be bent against the transverse flanges to lock the chokes to the transverse flanges permanently.

Finally, a frame construction procedure utilizing the connection techniques described above is used to construct a modular frame. First, the base footing is poured with the footing anchor bolts 22 in place for the columns. The column sleeve 30 is installed over the footing on top of the anchor bolt 22. The next step is to adjust the position of the column sleeve 30, level the column sleeve 20, and to fix the column sleeve 30 in place using the washer 26 and nut 28. After all column sleeves 30 are fixed, a level is used to mark out the base line on each column sleeve 30. Adjusting rings 34 are selected for the column sleeves 30 to adjust the bottom of the corresponding columns to the desired elevation or base line height. The columns 10 are positioned over the column sleeves 30 to rest on top of the adjusting rings 34 or the footing if there is no need for an adjusting ring. At this time, the holes on the columns should line up with the fixing holes 36 of the column sleeves 30 and fasteners are used to fasten the columns 10 to the respective column sleeves 30.

The next step is to connect the beams 12 to the columns 10 using any of the connecting mechanisms described above (see, e.g., FIGS. 3-5). Transitional column sleeves 100 or 110 are placed on top of the columns (as well as the beam to column connections), while ensuring that the distance between the fixing holes on the transitional column sleeve and the edge of the top of the lower column will match the holes on the bottom end of the upper column to be placed thereupon. The next step is to fix the beams to the columns by the chosen connecting mechanisms to make permanent connections (e.g., by hammering tight the choke 52 in FIG. 3). Floors are constructed on top of the installed beams 12.

To add another story, upper columns are placed on top of the transitional column sleeves 100 or 110 and fastened together. Beams are connected to the upper columns and then permanently fixed. Floors are constructed on top of the installed beams. These steps are repeated until the top story is constructed and the roof level is reached.

For roof installation, the connection mechanism utilizing the column cap 120 and truss/beam holders 124 of FIGS. 8-10, the mechanism utilizing the connecting member 150 of FIG. 11, the connection mechanism using the connecting member 160 of FIG. 12, the mechanism using protrusions 182 and key slots 184 of FIG. 13, and/or the mechanism using the truss holders 190 of FIG. 14 can be used. The top beams and/or roof trusses are then fixed to complete the frame construction.
